A reproduction device includes an acquisition unit, a reception unit, a reproduction unit, and an estimation unit. The acquisition unit acquires log information of a work machine, which is associated with time. The reception unit receives a reproduction instruction for an operation of the work machine. The reproduction unit reproduces the operation of the work machine, by sequentially applying angle information of the work machine that is included in the log information, to a work machine model in a case of receiving the reproduction instruction. The estimation unit estimates a work content of the work machine at each time, based on the log information.

A control unit is provided for controlling the dumping of a material entity from an implement of a working machine into a receiver. The control unit is adapted to determine a loading operation information including a current loading condition indicative of the distribution of the material that is currently accommodated by the receiver, and material characteristic information comprising one or more properties of the material of the material entity that is present in the implement. The control unit is adapted to, on the basis of the loading operation information, determine a dumping position within the receiver at which dumping position the material entity is to be dumped.

A hydraulic excavator acquires operation content frequency data in a designated period based on output values output from a plurality of sensors sensing parameters that serve as indicators of operation contents performed via an operation device. A storage section stores a plurality of guide screens each corresponding to one of a plurality of work patterns of the hydraulic excavator. A work identifying section searches actual result data in the storage section for actual result data that matches or is similar to the operation content frequency data acquired by the data acquiring section in terms of operation contents and frequency thereof, and that identifies a current work pattern based on a work pattern allocated to actual result data related to a result of the search. A display device displays a guide screen corresponding to the work pattern identified by the work identifying section among the plurality of guide screens.

The invention refers to a hydraulic control system for controlling operation of a work attachment of a work machine, comprising a controller configured to output a work attachment control value controlling the operation of the work attachment, an operator input device configured to output a command signal depending on the amount of actuation of the operator input device for setting the work attachment control value, a save input device configured to generate a save command signal upon actuating the save input device and a mode select input device configured to select a first mode and a second mode, wherein the controller is configured to save a constant work attachment control value, wherein the constant work attachment control value is the work attachment control value as set by the command signal upon receiving the save command signal.

An operation support system for a construction machine includes a memory that stores a program and a processor configured to execute the program stored in the memory to perform a process. The process includes generating multiple operation patterns or multiple arrangement patterns for the construction machine such that a rating regarding a predetermined target index becomes relatively high, obtaining environmental information of the construction machine to be supported, and outputting, based on the multiple operation patterns or the multiple arrangement patterns, an operation pattern or an arrangement pattern with which the rating regarding the predetermined target index of an operation of the construction machine to be supported becomes relatively high under an environment corresponding to the obtained environmental information.

A shovel (100) according to embodiments of the present invention includes a lower travelling body (1), an upper pivot body (3) pivotably mounted to the lower travelling body (1), an excavation attachment (AT) rotatably mounted to the upper pivot body, and a controller (30) provided to the upper pivot body (3). The controller (30) is configured to autonomously perform a compound operation including an operation of the excavation attachment (AT) and a pivot operation. The controller (30) may be configured to, in response to an automatic switch (NS2) provided in a cabin (10) mounted to the upper pivot body (3) being operated, autonomously perform the compound operation.

A work vehicle including a chassis, a ground engaging implement configured to move the chassis along a ground surface, a boom connected to the chassis, an arm connected to the boom, and a bucket connected to the arm. A first actuator rotates the boom with respect to the chassis, second actuator rotates the arm with respect to the boom, and a third actuator rotates the bucket with respect to the arm. A processor calculates a first cycle time of operation of the first actuator, and analyzes if the calculated first cycle time is valid. If the first cycle time is valid, the processor communicates the calculated first cycle time to a user, and if the first cycle time is not valid, the processor repeats the calculation of the first cycle time of operation of the first actuator.

Disclosed embodiments include power machines or loaders, and systems used on loaders, configured to augment the control of the loader to accomplish repetitive tasks. Also disclosed are methods of learning a task for augmented control of a loader, and methods of controlling a loader to perform a learned task to provide augmented control of the loader.

A method for controlling operation of a wood-handling device in a work machine. The wood-handling device is attached through a rotation device to an end of a set of booms of the work machine to create a desired orientation of the wood-handling device for the operation. The orientation of the wood-handling device using the rotation device is tied on the basis of the operation to be performed using the set of booms. The orientation of the wood-handling device is tied to the position of the end of the set of booms. The position of the end of the set of booms is defined while performing the operation, on the basis of the position of the end of the set of booms. The wood-handling device is oriented using the rotation device, according to the said tie.
